Self-washing station
The X series has a redesigned compact station and a detergent tank that is compatible with any detergent. The station features:
- Auto-empty. Sucks the dustbin's content into the disposable bag.
- Auto-fill water & detergent.
- Auto-wash the mopping pads and washboard. Older models do not wash the washboard and wash the pads with cold water. The latest do so with hot water.
- Drying the mopping pads. The mopping pads are getting dried with hot water after mopping.
The Dreame X50 Ultra washes and dries the washboard with warm water and hot air.
Mopping
- Rotating pads for mopping.
- Extend the mopping pad and a side brush along the walls, twist and delve as deep as 1.57in (4cm), reaching further hidden debris under furniture.
- Leaving the pads on the station automatically when not needed (except for the X30 Ultra)
- Dirt Detection makes the robot rewash the pads and remop dirty areas twice. These models use more water.
- Lifting the pads on the carpet.
- Lifting the roller in a mopping-only mode.
Dirt Detection senses how dirty the pads are after the mopping is done, washes them, and gets the robot back to mop the same area twice. The latest models are more precise at it.
*for a smoother mopping experience, get the model with a station that uses hot water for washing the pads.
Best value
The next gen has more power, dirt detection, and lifts the side brush.
Extends a side brush and mop to reach walls and corners
Compared to the X50 Ultra, the X40 Ultra lacks hot water self-cleaning, the ProLeap system, advanced navigation, and the newest brushroll system. However, it is still a good buy for the price.
Top tier
The Dreame X50 Ultra is equipped with the Industry-First ProLeap system, which is a step that helps the robot to climb up to 1.65in.
The ProLeap works the way of a two-layer threshold, where the gap between steps should be greater than 1.57in.
Upgrades over the X40 Ultra:
- Higher crossing ability
- Advanced dirt detection
- Stronger suction
- Dual brushroll system
- Rectracts LDS under furniture
- AceClean DryBoard self-cleans with hot water & dries the washboard after
- Hot water pads washing
Smart Dirt Detection 2.0 checks the water to find stains and gives them a deep clean. This tech can tell apart solids, liquids, or a mix, making sure every spot is gone for a perfect clean.
Depending on cleaning tasks, the robot lifts the roller, mopping pads, and a side brush. This is the only robot in the series that uses two rollers.
The first two roller systems (bristled & rubber) maintain hair tangles and do the job on carpet and hard floor surfaces
Cleaning mechanics upgrades:
- Better carpet cleaning because of stronger suction.
- Higher obstacles crossed thanks to the ProLeap.
- Efficient pick up with dual roller system.
- Reaches under most furniture when retracting the LDS tower.
- Leaves no residue on the washboard after washing.
The AceClean DryBoard cleans and dries the dashboard so it doesn't stink after mopping.
The Dreame X50 Ultra is a better buy compared to the previous generations.
Dreame L series compared
The L series is a wide range of robots starting with an affordable under $500 price tag, with an advanced self-cleaning station.

- new design station
- LED illumination in the dark
For a hundred dollars more, you get a smarter robot that lifts the roller on spills, has a different base, automatically removes the pads, and has Dirt Detection.
Navigation and cleaning upgrades:
- Advanced obstacle avoidance by using AI and illuminating the area in the dark.
- Removes the mops when they are not needed
However, compared to the L10s Pro Ultra, the L20 Ultra does not use hot water for washing.
